Orchid Fertilizer - Feed ME! MSU - RO/Rain/Tap Water (Quart)

Easy to use and my orchids love it!

I’ve been using the granular version of this fertilizer for about 2 1/2 years. Got lots of root and leaf growth but only one flower spike. It also changed color from agua to a greyish yellow despite storing it properly. So I thought I’d try the liquid version. I feed via the weekly weakly method. After 3 applications and 1 flush cycle I have an orchid that produced a flower spike, IN WINTER!!! This particular plant was purchased in May 2020 and hadn’t re-bloomed at all until now! This liquid fertilizer is amazing! All of my orchids look super healthy and I wouldn’t be surprised if I see more flowers soon. Highly recommend this liquid fertilizer! 3-10-23 her buds are opening up!

Your orchids will thrive.

Michigan State University studied and produced this fertilizer. Great stuff.

MSU is the standard by which all other fertilizers are measured. This product is used in commercial greenhouses where quality is a necessity. In the smaller containers, such as the one quart liquid, it is well suited to the hobby grower. I use this product for my orchids and have had good results. My plants flower and they grow with sturdy bulbs and shoots. The standard dosing is, I believe, one teaspoon per gallon of water. For orchids, though, the recommendation is water more frequently but at a lower dosage of maybe 1/4-1/2 of the recommended concentration (and, at this concentration, one quart will last you quite a while). One issue that all fertilizers have is that they raise the amount of total disolved solids (TSD) in the water. This is bad for the plant as it will, at higher concentrations, burn the roots of the plants. Orchids are particularly prone to this burning. The MSU formulation does not raise the level of TSD too much (from my normal tap water level of 135ppm to about 350ppm at 1/2 concentration) so it does not harm the plants. For orchids, you still need to flush the plants with plain water every fourth feeding or so. There are several versions of this fertilizer so be sure to get the formulation that is built for your kind of water (note that this review is for the formulation designed for tap water). The other formulations have somewhat different mineral content to compensate for the minerals expected in various water sources. The original formulation I purchased was a pink liquid. It appears the formulation has been somehow changed now to a green liquid. Seems that all the nutirents are there though. The only issue I have with this product is the packaging. The picture shows a cylindrical bottle. The last shipment I received was in a rectangular bottle. Now, one ordinarily expects that would make no difference. However, I found that the new bottle tended to splash liquid about when it was very full. Also, the sides tended to collapse so that more liquide was squished out.

easy to use, and results using the proper portions, and fed regularly are amazing

This is the only brand that has reliably led to new spikes and buds for me over the last five years. This is the best value especially if you’ve already bought the 4oz stopper bottle.

Great
